The stockAdapter seam built in v1 finally eats. Lane E's stock pack (parody-
transformed Discogs metadata + cover atlas) feeds record-shop bins + the dig
riffle behind ?stock=real. Economy stays a stub (buying = toast).
- Contract handshake (task 1, unblocked E): confirmed E's index schema as-is
in LANE_C_NOTES (items[{id,title,artist,price,price_band,atlas,uv}]; uv
origin top-left, C flips V for WebGL; fail-soft; per-type packs).
- stockpack.js (new): preloadStockPack/getStockPack (cached) + makeStockAdapter.
Atlas texture + material are shared/cached (like depot GLBs); each sleeve is
a cover PLANE sampling the atlas at its baked UV, so all real sleeves in a
room batch to ONE draw (record: 59 draws).
- stock.js binFan: real cover planes (else parody canvas). dig.js: riffles real
covers, pull card shows title/artist/$price/band. interiors.js: opts.stock=
'real' wires the adapter (warn-once + parody fallback if pack absent). Test
page reads ?stock=real, preloads record/book/toy, passes the adapter to the dig.
Validated (E's staged 24-sample; real covers drop in unchanged when E gets the
DB): determinism 0/30, leak-free rooms + real dig (0/0 over 25 cycles), draws
<=139 all rooms (record 59), fail-soft on no-pack types, ?dig=1&stock=real
leak-free. Flag-off + ?noassets untouched (procedural path byte-identical).
qa.sh --strict GREEN. F smoke hook + E contract in LANE_C_NOTES. Shot

# LANE C — cross-lane notes (PROCITY-C)
|
||
|
||
## → Lane F: `?stock=real` smoke for the strict harness (round-7 C1 landed)
|
||
|
||
`?stock=real` is wired (record shops; book/toy fail-soft if E ships those packs). Smoke recipe:
|
||
- Preload once: `import { preloadStockPack } from interiors.js; await preloadStockPack('record')`.
|
||
- Boot `?stock=real`, enter a record shop, **assert real sleeves present**: a real sleeve is a `Mesh`
|
||
with `userData.isStock`, geometry `PlaneGeometry`/`BufferGeometry` (batched), on a shared **atlas**
|
||
material (`material.map` = the pack atlas, not a per-item canvas). Simplest assert: after build,
|
||
`let n=0; room.group.traverse(o=>{ if(o.userData?.isStock && o.material?.map) n++ }); assert n>0` — with
|
||
the pack loaded the record bins' sleeves batch to **one** atlas mesh (parody canvas would be ~6 card
|
||
meshes). Or open the dig (`?dig=1&stock=real`) and assert a pulled sleeve's panel title is a pack title.
|
||
- **Fail-soft**: pack missing → parody canvas + one `console.warn` (no throw). `?noassets` unaffected.
|
||
- **drawSweep still ≤350** with `?stock=real` (record 59 draws — the atlas batches all sleeves).
|
||
|
||
## → Lane E: stock-pack contract CONFIRMED (round-7 C1) — build the real pack to this, unchanged
|
||
|
||
Your proposed index schema is good — **confirmed as-is, no field changes**. Building `?stock=real`
|
||
against your staged 24-sleeve sample now (`web/assets/models/stock_record_{index.json,atlas_00.webp}`);
|
||
the real covers drop in unchanged. The contract C consumes:
|
||
|
||
```jsonc
|
||
// stock_<type>_index.json (type ∈ record | book | toy ; record is the acceptance bar)
|
||
{
|
||
"version": 1,
|
||
"atlas_px": 2048,
|
||
"cell": 256, // informational; C reads uv, not cell
|
||
"atlases": ["stock_record_atlas_00.webp", ...], // 1+; may be depot: or assets/models/ resolved
|
||
"items": [
|
||
{ "id": "rec_0000",
|
||
"title": "Neon Suburbs", // parody-transformed (no-real-trademarks law applies to metadata)
|
||
"artist": "Trev Wollemi",
|
||
"price": 39, // integer dollars — C shows "$39"
|
||
"price_band": "collector", // bargain|standard|collector|grail — C may tint the sticker
|
||
"atlas": "stock_record_atlas_00.webp", // which entry in `atlases`
|
||
"uv": [0.0, 0.0, 0.125, 0.125] } // [u0,v0,u1,v1] cover rect, ORIGIN TOP-LEFT
|
||
]
|
||
}
|
||
```
|
||
|
||
Agreements / who-does-what:
|
||
- **UV origin is top-left (image-natural) — C flips V for WebGL** (`v_gl = 1 - v`). Keep your index
|
||
image-natural; the consumer handles the flip. (Sample verified against this.)
|
||
- **Resolution**: C loads `stock_<type>_index.json` from a base (default `assets/models/`, i.e. your
|
||
staged path — same-origin, works offline). Atlas filenames in the index resolve against the same base;
|
||
if you publish atlases to the depot, give me a `"depot": true` flag or depot-prefixed names and I'll
|
||
route through the `depot:` loader. For now the sample loads local.
|
||
- **Seeded pick per bin is mine** (same `shop.seed` → same crate contents). I only need *enough* items —
|
||
24 repeats across bins (fine for testing); the 300 pack fixes variety.
|
||
- **Batching**: because every sleeve samples one shared atlas material (per-item UV baked into geometry),
|
||
all real sleeves in a room merge to **one draw** — the ≤350 law holds. Please keep it **one atlas per
|
||
pack** where you can (or few); each extra atlas = one more draw.
|
||
- **Fail-soft**: index/atlas missing or `?stock` off → parody canvas (warn once). `?noassets` untouched.
|
||
- **Per-type packs**: name them `stock_book_*`, `stock_toy_*` if you build them; I key by shop type and
|
||
fail-soft per type, so record-only is fine — book/toy are a bonus.
|
||
|
||
You flagged needing a Postgres DSN (from John/Fable) to swap synthetic covers for real Discogs images —
|
||
that's external and **does not block my consumer**; ping me only if the schema needs to change.
|
||
|
||
|
||
|
||
## → Lane F: interior ≤350-draw assertion for the harness (round-6 C1)
|
||
|
||
C1 batching landed — worst room is now **313 draws GLB-on** / 152 GLB-off (was 1,245). The test page
|
||
exposes the assertion for your harness:
|
||
|
||
- `window.PROCITY_C.drawSweep({ glb: true|false })` → `{ worst, worstAt, pass, law: 350, perType }`.
|
||
Builds every shop type × archetype at seed 1990, renders each, returns the worst `renderer.info.render.calls`.
|
||
It's already folded into the interior soak's PASS/FAIL. For your smoke/soak gate, call it with
|
||
`glb:true` (the tighter case) and assert `pass` (`worst <= 350`). Headless-safe, ~1s.
|
||
- The draw law is a Lane-C constant (`DRAW_LAW = 350` in interior_test.html) so it's one number to bump
|
||
if the budget ever changes. Ping me if you'd rather it read from a shared config.
|
||
|
||
## → Fable / Lane F: v1.1 is ready (round-5 C1 done)
|
||
|
||
**C1 committed.** Lane E's re-exports are mapped + validated in `web/js/interiors/glb.js`:
|
||
- `record_crate` (fixed) → record bins/crates upgrade to plastic crates with the procedural sleeves.
|
||
- `counter → counter_till` → the real ~1.6 m counter-with-till drops in; footprint-fit + floor-plant
|
||
unchanged; **keeper-stand pose still valid** (it's a room-local pose, not tied to the counter geometry).
|
||
- **No double till**: my separate `cash_register` counter-top attach is dropped whenever `counter_till`
|
||
is live (that GLB has its own till). `milkshake_mixer` still on the milk-bar bench.
|
||
- GLB soak: `0 throws / 0 path / 0 determinism / leak-free / worst 10.4 ms`, **0 rooms with a visible
|
||
primitive till**. Primitive path byte-unchanged (C1 touched only `glb.js`). `qa.sh --strict` green.
|
||
|
||
**→ You can tag v1.1** per ROUND5 §Lane C acceptance ("bins + counter GLB-live, no double till, soak
|
||
green → F tags v1.1"). Evidence: [`docs/shots/laneC/glb_v1_1_r5.jpg`](../shots/laneC/glb_v1_1_r5.jpg),
|
||
report in [`LANE_C_GLB_VALIDATION.md`](LANE_C_GLB_VALIDATION.md).
|
||
|
||
## → Lane F: input/mode hook I need for `?dig=1` (round-5 C2)
|
||
|
||
The crate-riffle (dig) is interior-mode-only and needs the shell to tell an interior when the player
|
||
interacts with a fitting. Proposed seam (you own the shell/`interior_mode.js`):
|
||
|
||
- On the player pressing the interact key while aimed at a fitting whose `userData.kind === 'bin'`
|
||
(record bins expose `places:[group]` with `userData = { kind:'bin', interactable:true }`), call a
|
||
hook the interior optionally provides: **`room.onInteract?.(hitObject)`** — where `room` is the object
|
||
returned by `buildInterior(...)`. If it returns truthy, the shell should suppress normal movement /
|
||
pointer-lock until the interior calls back that the dig closed (I'll expose `room.digActive` +
|
||
fire a `procity:digClosed` event, or a callback you pass in — your call on the exact contract).
|
||
- Gate the whole thing on `?dig=1` (I read the flag inside the interiors lib; when off, `onInteract`
|
||
is absent and nothing changes — flag-off boot stays byte-identical).
|
||
|
||
I'm building the dig against my own test page (`web/interior_test.html`) with a direct click handler in
|
||
the meantime, so it's testable without the shell. Tell me if you'd prefer a different hook shape and
|
||
I'll match it. — PROCITY-C
